Nice to hear it worked! Did you have to do any modifications
in order to get it running? The only Seagate drive I used it
with was an old ST15150 4GB drive... 

Did you receive .sea files from Seagate? Did they have a 
length of n * 512 + 80 bytes? I am just asking because I'd
like to know if the 80 bytes header ist still present...

Thanks,
